The tip of the output lever h of the actuator f and the locking lever 1 are connected by a connecting wire m (iron bar), where r is an inside open lever and t is a window glass.

(Problems to be Solved by the Invention) In the known device, a vertically rotating part of a rocking lever 1 mounted on an upper part of a standing part d and a vertically moving tip of an output lever h are connected by a connecting wire m. However, there is a problem in that the locking lever 1 is configured to rotate up and down when the output lever h moves up and down.

In the case of this structure, since the connecting wire m is located in the vicinity of the passage in which the window glass t goes up and down, the lock is attached with great care so that the window glass t and the connecting wire m do not come into contact with each other. Be careful. In the present invention, due to a special ingenuity, the structure of the connecting wire m that engages the vertically rotating portion of the locking lever 1 and the vertically moving tip of the output lever h is changed so that the lock mounting position is slightly displaced. In this case, the window glass t and the connecting wire m are not in contact with each other.

(Means for Solving the Problems) Therefore, the present invention provides a lock having a latch that engages with a striker on the vehicle body side to rotate normally when the door is closed, and a ratchet that engages with the latch and prevents reverse rotation of the latch. Body 1
A metal back plate 3 in which a pair of left and right is bent in the front-back direction to form an upright portion 5 is provided on the back surface side of the, and an actuator 7 is fixed to a lower position of the upright portion 5, and the actuator 7 has a left-right direction. An output shaft 8 is provided, and a base portion of a rear end of an output lever 9 whose front end portion moves up and down is fixed to the output shaft 8. A horizontal shaft 13 is provided at an upper position of the upright portion 5.
The locking lever 14 pivotally displaced between the locked position and the unlocked position is axially stopped by the lock body 1, and the shaft 16 in the front-rear direction is provided on the rear surface side of the lock body 1 and has a long hole 18 extending in the up-down direction. Open lever 15 with 19
And a projection 26 formed so as to project near the lower portion of the long hole 18 and a part of the projection 26 are connected to a ratchet, and when rotated, the ratchet lever 17 that can disengage the ratchet from the latch is pivoted, An upper end of a link 21 which is long in the vertical direction is locked at a side position of the shaft 13 of the locking lever 14, and the open lever 15 is attached to a lower end 24 of the link 21.
The locking lever is provided with a lower slide pin 25 in the front-rear direction that engages with a vertically elongated hole 18 of one piece 19 of the strip 19 so as to be vertically movable.
When 14 is in the lock position, the lower slide pin 25 moves upward in the elongated hole 18 and is displaced to a position outside the protrusion 26, whereby the open lever 15 rotates and the lower slide pin moves. Even if the moving pin 25 is moved sideways, the ratchet lever
When the locking lever 14 is in the unlocked position, the lower sliding pin 25 moves downward in the elongated hole 18 and is displaced to a position where it overlaps with the side portion of the protrusion 26 when the locking lever 17 is not rotated. As a result, when the open lever 15 rotates to move the lower slide pin 25 laterally, the ratchet lever 17 rotates to open the door, and the actuator 7
The lower end of the connecting fitting 30 is axially fixed to the tip of the output lever 9 by the lower connecting pin 38 in the left-right direction, and the upper end of the connecting fitting 30 is axially fixed in the vertical intermediate position of the link 21 by the upper connecting pin 33 in the front-back direction. In the above, the lower connecting pin 38 is loosely inserted as a long pin, and an elastic member 39 is interposed between the output lever 9 and the linking metal fitting 30 to form a vehicle lock device.

(Embodiment) An embodiment of the present invention will be described with reference to the drawings. Reference numeral 1 denotes a lock body mounted on the door 2 side. When the door is closed inside the lock body 1, the latch engages with a striker on the vehicle body side and rotates normally. And a ratchet that engages the latch to prevent reverse rotation of the latch.

Reference numeral 3 denotes a metal back plate attached to the back side, and the left and right panel 4 sides of the back plate 3 are bent at right angles to form an upright portion 5 in the front-rear direction.

A mounting member 6 protruding along the panel 4 is fixed to a lower position of the standing portion 5, and an actuator 7 is fixed to a tip of the mounting member 6. The output shaft 8 of the actuator 7 is a left-right shaft, and the base of the rear end of the output lever 9 which rotates up and down is fixed to the protrusion on the opposite side of the panel 4.

The actuator 7 is provided as close to the panel 4 as possible. Therefore, the mounting bracket 6 is provided by bending the middle portion so as to approach the panel 4 side, and the actuator 7 is attached to the tip of the mounting bracket 6. The output lever 9 also has a bent portion in the middle portion so that the tip end side thereof is close to the panel 4.
10 is formed (FIG. 7), and a through hole 12 is formed at the front end 11 of the output lever 9.

A rocking lever 14 is axially fixed to an upper position of the upright portion 5 by a left-right shaft 13. The locking lever 14 rotates about the shaft 13 between the locked position and the unlocked position by operating the sill knob. Further, when the output lever 9 of the actuator 7 is rotated up and down, the output lever 9 is similarly rotated about the shaft 13.

15 is an open lever (Fig. 4), which is a shaft 16 in the front-back direction.
Thus, the lock body 1 is axially fixed to the back side. A ratchet lever 17 (Fig. 3) is also fixed to the shaft 16. The open lever 15 has one piece 19 having a long hole 18 extending in the vertical direction and protruding downward, and another piece 20 protruding in the panel 4 direction.
On the side of the shaft 13 of the locking lever 14, an upper pin 23 in the left-right direction formed on the upper end 22 of a vertically long link 21 formed of synthetic resin is engaged with an engaging shaft, and formed on the lower end 24 of the link 21. The lower slide pin 25 in the front-rear direction is vertically movably inserted into the elongated holes 18 of the upper and lower open levers 15, and when the locking lever 14 rotates to the lock position, the lower slide pin of the lower end 24 of the link 21. When the locking lever 14 is rotated to the unlock position, the lower sliding pin 25 at the lower end 24 of the link 21 moves the lower sliding pin 25 to the elongated hole 18 and moves to the locked position.
Of the ratchet lever 17 to the side of the projection 26 of the ratchet lever 17 at the unlock position. When the lower end 24 of the link 21 overlaps with the protrusion 26 of the ratchet lever 17, the protrusion 26 is rotated by the rotation of the open lever 15 to rotate the ratchet lever 17, and when the ratchet lever 17 rotates, it becomes a latch as is known. The engaged ratchet can be released from the latch to open the door.

The link 21 extends vertically between the movement locus of one side edge 28 of the window glass 27 and the back side of the lock body 1, and an engaging hole 29 is formed at an intermediate position thereof. The engagement hole (32) formed in the upper ends of the upper and lower rods (31) of the connecting fitting (30) is overlapped to insert the upper connecting pin (33) and fix the shaft. The upper and lower rods 31 are located between the one side edge 28 and the lock body 1 so as not to interfere with the vertical movement of the window glass 27.

Below the upper and lower rods 31, a horizontal projecting rod 34 extending in the direction of the through hole 12 at the tip of the output lever 9 that moves in an arc shape in the vertical direction is provided, and an intermediate portion of the horizontal projecting rod 34 is spaced from the tip 11. A bent portion (35) is formed on the inner surface of the lateral projection rod (34), and a through hole (37) is formed at a tip (rear end) (36) of the lateral projection rod (34).

A slightly longer lower connecting pin 38 is inserted into the through hole 12 and the through hole 37, and a coil spring 39 as an elastic member is interposed between the through hole 12 and the through hole 37. The reason why the lower connecting pin 38 is made long is to absorb the twist due to the deviation of the rotational loci of each other. 40 is an inside turning lever, one piece of which 41
Engages below the other piece 20 of the open lever 15.

(Operation) Next, the operation will be described.

When the output shaft 8 of the actuator 7 rotates, the tip of the front end of the output lever 9 rotates vertically, and the horizontal projecting rod 34 of the connecting metal fitting 30 is moved up and down via the lower connecting pin 38 so that the horizontal projecting rod 34 is integrated with the horizontal projecting rod 34. The upper and lower rods 31 are also moved up and down and linked via the upper coupling pin 33.
Move 21 up and down while in the locked or unlocked position,
When the lower sliding pin 25 of the lower end 24 of the link 21 moves to the upper part of the elongated hole 18, it separates from the protrusion 26 and becomes the lock position, and at the same time, the upper locking lever 14 is rotated to the lock position, and the lower end 24 of the link 21 When the lower sliding pin 25 moves to the lower part of the long hole 18, the lower sliding pin 25 overlaps with the protrusion 26 to be in the unlock position, and at the same time, the upper locking lever 14 is rotated to the unlock position.

At the locked position, the door open / close door handle open operation
Rotate the open lever 15 around the front-rear axis 16 to make it a long hole.
Even if the lower sliding pin 25 is moved laterally by 18, the lower sliding pin 25 does not abut the projection 26 of the ratchet lever 17 and is idle, so the ratchet lever 17 does not rotate. The door cannot be opened because it cannot be opened and remains engaged with the latch.

At the unlocked position, when the open lever 15 is rotated around the longitudinal axis 16 by the opening operation of the inside / outside door handle, the lower slide pin 25 is moved laterally by the elongated hole 18, and the lower slide pin 25 is moved. The projection 26 of the ratchet lever 17 is pushed by the lateral movement of the ratchet lever 17, so that the ratchet lever 17 rotates, and the ratchet is released from the latch to open the door.

In the above case, the output lever 9 of the actuator 7 rotates around the output shaft 8 to make a circular arc up and down, but the connecting fitting 30 attached to the link 21 only moves up and down together with the link 21. Although the twisting phenomenon occurs between the tip of the connector and the connecting fitting 30, the present invention has a loose structure between the output lever 9 and the connecting fitting 30, so that the twisting is absorbed and the operation is smoothly performed. Further, since a long lower connecting pin 38 is inserted into the portion and the shaft is fixed by interposing an elastic member 39 such as a spring, the twist is smoothly absorbed.

In addition, when the window glass 27 is moved up and down, the window glass 27 moves the locking lever 14, the inside rotation lever 40,
In the case of the publicly known example, there is a concern that the connecting wire m passed between the locking lever and the output shaft may come into contact with the mounting bracket 6 and the coupling bracket 30 and the like. Since the upper end of the upper and lower rods 31 of the connecting metal fitting 30 corresponding to the connecting wire m is locked in the upper and lower middle of the link 21, the window glass 27 is provided in a relatively large space and the upper and lower rods 31 and the window glass 27 are connected to each other. Prevent contact.

(Effect) The present invention is provided on the back surface side of the lock body 1 having a latch that engages with a striker on the vehicle body side when the door is closed and rotates normally, and a ratchet that engages with the latch and prevents the latch from rotating normally. A metal back plate 3 in which one of the left and right sides is bent in the front-back direction to form an upright portion 5 is provided, an actuator 7 is fixed to a lower position of the upright portion 5, and the actuator 7 has a left-right output shaft. The output shaft 8 is provided with a base portion at the rear end of an output lever 9 whose front end portion moves up and down, and at the upper position of the upright portion 5, a lock position and an unlock position are provided by a horizontal shaft 13. An open lever having a locking lever 14 pivotally displaced to a position and having a downwardly projecting piece 19 having a long hole 18 extending in the vertical direction formed by a shaft 16 in the front-rear direction on the back side of the lock body 1. 15 and below the long hole 18 Projections formed to project so as to face the vicinity of 26
And the ratchet lever 17 that is partially connected to the ratchet and can rotate to disengage the ratchet from the latch, and the shaft 13 of the locking lever 14 is locked.
The upper end of a link 21 which is long in the vertical direction is locked at the side position of the front and rear ends of the lower end 24 of the link 21 which is vertically movably engaged with the vertical hole 18 of the piece 19 of the open lever 15. Direction lower slide pin 25 is provided, and when the locking lever 14 is in the lock position, the lower slide pin 25 moves upward in the elongated hole 18 and is displaced to a position separated from the protrusion 26. Thus, even if the open lever 15 rotates to move the lower slide pin 25 laterally, the ratchet lever 17 does not rotate, and the lower slide moves when the locking lever 14 reaches the unlock position. Pin 25 is the long hole 18
When the lower lever pin 25 is moved laterally by pivoting the open lever 15 by moving it downward to a position where it overlaps the side portion of the protrusion 26, the ratchet lever 17 is moved.
Allows the door to be opened by pivoting, and the lower end of the connecting fitting 30 is axially fixed to the tip of the output lever 9 of the actuator 7 by the lower connecting pin 38 in the left-right direction, and the upper end of the connecting fitting 30 is joined in the upper-back direction. When the link 33 is axially fixed to the upper and lower intermediate positions of the link 21, the lower coupling pin 38 is loosely inserted as a long pin, and an elastic member 39 is interposed between the output lever 9 and the coupling fitting 30. The output lever 9 of the actuator 7 rotates around the output shaft 8 to make an up-and-down arc rotation because it is the locked device for a vehicle. However, the connecting fitting 30 attached to the link 21 moves up and down together with the link 21. Therefore, the tip of the output lever 9 and the connecting bracket
Although the twisting phenomenon occurs between 30 and 30 in the present application, the output lever 9 and the connecting fitting 30 are connected in a rattling structure, so that the twisting is absorbed and the operation is smoothly performed. Further, since a long lower connecting pin 38 is inserted into the portion and the shaft is fixed with an elastic member 39 such as a spring interposed, the twist is smoothly absorbed. Further, when the window glass 27 is moved up and down, the window glass 27 moves up and down in the vicinity of the locking lever 14, the inside rotation lever 40, the mounting bracket 6, the connecting bracket 30, etc. There was a concern that the connecting wire m passed between the output shaft and the output shaft may come into contact with the connecting wire m. Therefore, the windshield 27 is provided in a relatively large space, and the upper and lower rods 31 and the windshield 27
Prevent contact with.
